I am very sorry for my error. (If my eyes are correct) From the mailling list mails, this patch shouldn't be applied to 4.19 5.4 5.10 5.15 6.1 6.6, and these branches should perform a revert operation. Reason for revert: In commit dfe6c5692fb5, I mistakenly wrote: "This bug has existed since the initial OCFS2 code.". The statement is wrong. The correct introduction commit is 30dd3478c3cd. IOW, if the branch doesn't include 30dd3478c3cd, dfe6c5692fb5 should also not be included. I am not sure whether the revert and resubmit patch operations are correct or not. Please guide me if the approach is incorrect. Heming Zhao (2): ocfs2: Revert "ocfs2: fix the la space leak when unmounting an ocfs2 volume" ocfs2: fix the la space leak when unmounting an ocfs2 volume
